Objective:

To investigate the associations between sleep reactivity, psychological resilience, and insomnia symptoms among young Chinese male university students.

Approach:

• Participants: 1,122 male participants (Mean age = 21.13, SD age = 1.48) were included in the study.
• Assessment Tools: The Ford Insomnia Response to Stress Test, Insomnia Severity Index, and Connor-Davidson Resilience Scale were used to assess sleep reactivity, insomnia symptoms, and psychological resilience.
• Analysis Methods: Multiple regression analyses were conducted to compare main and moderating effects of three resilience dimensions—Tenacity, Strength, and Optimism. A moderated network model was also estimated.

Key Findings:

• Greater sleep reactivity was associated with more severe insomnia symptoms.
• Strength showed a negative association with insomnia symptoms and significantly moderated the relationship between sleep reactivity and insomnia symptoms.
• Moderated network analysis indicated that Strength moderated specific connections between sleep reactivity components and insomnia symptoms, particularly those related to interpersonal conflict and public speaking.

Limitations:

• The study focused solely on young male university students, limiting generalizability.
• The cross-sectional design does not allow for causal inferences.
